CHARLES D. ONEIL AND ALFRED S. BEATY, OF CHARLESTON, WES'I` VIRGINIA.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 600,648, dated March 15, 1898.

Application filed May 6, 1897- Serial No. 635,392. (No model.)

To @ZZ whom it may concern:

Be it known that we, CHARLES D. ON EIL and ALEREDS. BEATY, citizens of the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Nut-Locks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has relation to nut-locks.

The object of the invention is to provide a simple, inexpensive, and durable nut-lock which may be easily attached and will eectually prevent accidental unscrewing of the nut.

With this object in view the invention consists of certain features of construction and combination of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l is -a front View of our improved nut-lock, showing its application. Fig. 2 is a transverse sectional view through the locking-plate and washer. Fig. 3 is a detail perspective view of the locking-plate removed. p

In said drawings, 1 denotes a bolt; 2, the nut; 3, the washer, and 4 the locking-plate.

The washer is provided with side iianges 5, forming V-shaped grooves 6. These flanges converge from the outer to the inner end of the washer, giving it a slightly wedge-shaped appearance. The locking-plate is provided with V-shaped side ribs 9, which are adapted to the grooves of the washer, and is also provided with a nut-recess 10, the walls of which are adapted to embrace the angles of a nut. The plate beyond this nut recess carries spring-prongs 11, having on their outer edges studs 12, which are adapted to spring into corresponding sockets 13, formed in the flanges of the washer, and thereby prevent the acci-vy dental jarring of the plate from the washer.

In inserting the plate in position it is driven down at the sides of the nut, and when the studs 12 thereon arrive opposite the recesses 13 in the anges of the washer the prongs which have been sprung inward by the converging side flanges will force the studs into the recesses, thereby rmly locking the plate in position.

Having thus fully described our invention, what we claim as new, and desire to secure by LettersfPatent of the United States, is-

A nut-lock comprising a washer having converging side fianges provided with V-shaped grooves, and with recesses or sockets, and a locking-plate having a nut-recess and carrying prongs, the sides of said looking-plate being provided with V-shaped ribs adapted to the grooves of the washer, and with studs to enter the recesses in said grooves, substantially as set forth.

In testimony whereof we hereunto aiiix our signatures in presence of two witnesses.
